Description

The collocation method of information feedback and device, measurement, feedback method and device

Technical field

The present invention relates to information feedback technology, relate in particular to feedback method and the device of a kind of collocation method of information feedback and device, the method for measurement based on information feedback configuration information, channel status.

Background technology

Long Term Evolution (LTE, Long Term Evolution) system, after having experienced the several versions of R8/9/10, has proposed again R11 technology.At present part R8 product starts progressively commercially, and R9 and R10 need further product programming.

Experiencing R8 and R9 stage, R10 has increased again a lot of new characteristics on the above two basis, demodulated reference signal (DMRS for example, Demodulation Reference Signal), channel state information reference signals (CSI-RS, Channel State Information Reference Signal) the pilot tone characteristic such as, the transmission such as 8 antenna supports and feedback characteristics etc., particularly presence of intercell interference is offset and is strengthened (eICIC, ehanced Inter-Cell Interference Cancellin) technology is being considered on the basis of R8/9ICIC, further consider the interference avoidance technique between community.For the technology that solves interference problem between community, at the R10 initial stage in stage, mainly consider that the area interference under homogenous networks avoids, wherein the consideration eICIC technology of main flow and multipoint cooperative (CoMP, Coordinated Multi-point) technology.CoMP is as the term suggests be exactly that a plurality of node cooperations send data to one or more UE at identical running time-frequency resource or different running time-frequency resources.This technology can reduce the interference between community, improves the throughput of cell edge, expands community and covers.But introduced more scene owing to having considered heterogeneous network in the discussion later stage, the time restriction that the complexity of CoMP technology and R10 discuss, final decision is not introduced extra CoMP standardized content in the R10 stage, but the demand that can consider CoMP part at design CSI-RS designs, so CoMP technology is not just carried out further discussion after 60bis meeting.

At R11, be discussed the initial research stage (SI, Study Item), mainly by planning scene and the various transmission technologys of CoMP, determine unified assessment framework, the CoMP by two stages assesses to prove that CoMP technology can obtain obvious performance gain.Completing recently CoMP SI conclusion, be need to be to the joint transmission (JT in CoMP technology, Joint Transmission), (DPS is selected in dynamic cell, Dynamic Point Selection), cooperative scheduling (CS, Coordinated Scheduling), cooperative beam figuration (CB, Coordinated Beamforming) are further studied.

What need before to the various technical research of CoMP first to consider is which difference is CoMP technology have for R8/9/10 technology, comprising the control signal of CoMP, how to support the notice of CoMP measuring assembly, how to support the demand of the different transmission technologys of CoMP, if UE measures and reports the channel information (CSI, Channel State Information) of a plurality of nodes etc.Wherein how to measure and report the CSI of a plurality of nodes are one of matters of utmost importance of solving of CoMP Technology Need to UE.The current discussion of feedback of CoMP mainly can be divided into periodic feedback and aperiodicity feedback, aggregated channel information feedback and non-polymeric feedback of channel information.So-called aggregated channel information feedback refers to the channel information that the channel information of a plurality of nodes is aggregated into a node and carries out global feedback.As measuring assembly comprises two nodes, the channel information H1 of node 1, the channel information H2 of node 2, two node channels of the at this moment first polymerization of UE are a large channel information H=[H1; H2], then measuring correlation computations feedback.Non-polymeric feedback of channel information can be divided into again separate single community feedback and separate single community feedback adds minizone control information.So-called separate single community feedback refers to according to the channel information of each node independently measures correlation computations feedback.So-called separate single community feedback adds minizone control information and refers to according to the channel information of each node and independently measure correlation computations, and calculates each internodal phase place and/or amplitude information and feed back.For aggregated channel information, comprising aggregated channel quality, indicate (CQI, Channel Quality Indicator) feedback, polymerization CQI refers to that the CQI of UE side feedback is the polymerization CQI that corresponding one or more CSI-RS configuration information is measured, UE utilizes a plurality of CSI-RS configuration informations to find the time-frequency position of corresponding CSI-RS, thereby measure the interfere information that obtains precoding weights information and utilize other pilot tones to obtain, calculate, at this moment UE is that node corresponding to one or more CSI-RS configuration information of supposition sends data to it, thereby obtain these a plurality of nodes and combine the corresponding CQI value of transmission.Due to polymerization CQI may be corresponding the polymerization of measuring of or CSI-RS configuration information, for example measuring assembly is being good at enough comprising 3 CSI-RS configuration informations, at this moment CSI-RS configuration information of polymerization has 3 kinds of possibilities, two CSI-RS configuration informations of polymerization have three kinds of possibilities, CSI-RS configuration information of polymerization has a kind of possibility, seven kinds of possibilities, so have multiple possibility for polymerization CQI, do not have a kind of possibility can be called polymerization possibility altogether.

For traditional R8/R9/R10 user owing to only need to feeding back the CSI of Serving cell, so need to consider single cell capacity for periodic feedback and non-periodic feedback on same carrier wave, particularly for Physical Uplink Control Channel (PUCCH, Physical Uplink Control Channel), only need the feedback of Dui Dan community to be optimized.Consider at present coding, mixed self-adapting request retransmission (HARQ, Hybrid Adaptive Request Retransmission) bit number etc., for a UE maximum CSI feedback of supporting 11 bits in a Physical Uplink Control Channel (PUCCH, Physical Uplink Control Channel) sub-frame of uplink.The composition maximum of 11 bits can be considered the pre-coding matrix indication (PMI of 4 bits, Precoding Matrix Indicator) and the channel quality of 7 bits of two code words indication (CQI, Channel Quality Indicator) (considering the differential feedback of CQI between different code words).CoMP, due to the CSI feedback that will consider for a plurality of communities, require the PUCCH capacity of N*11 bit, but current PUCCH capacity cannot meet this requirement, so need a set of rational feedback scheme to solve the not enough problem of PUCCH capacity.What easily expect is compressed feedback signaling, but CoMP has higher requirement, particularly JT or even JT-MU CSI accuracy to be proposed to high requirement for the precision of CSI, so the performance loss that compression causes may cause the decline of CoMP performance gain.Another consideration may be the capacity that improves PUCCH, need to redesign the feedback format of PUCCH, will certainly bring larger standardization effort like this.If, for the difference and the self adaptation switching that may need to guarantee different mode of CSI feedback request, this Feedback Design may be just more complicated between the different mode of consideration CoMP.So consider under discussion to introduce the concept that can guarantee the internodal information that cooperation transmission pattern is switched flexibly and/or introduce polymerization CQI.Polymerization CQI is discussed in recent meeting and can obtains and introduce the similar performance of internodal information+polymerization CQI, at this moment introduce without comparison the feedback of information between extra node, meeting at present is also continuing to discuss the feedback whether node saves information.But at above two schemes, all considered to introduce the concept of polymerization CQI.Concept for polymerization CQI is to feed back the CQI value that a plurality of node aggregations produce, the interstitial content of its polymerization can be the combination of an arbitrary number node of all nodes in measuring assembly, for example in measuring assembly, comprise six nodes, at this moment possible combination comprises 63 kinds of situations, if consider the aggregation number that restriction is maximum, combination at this moment comprises 41 kinds of possibilities.If UE once feeds back or a plurality of subframe is fed back a plurality of polymerization CQI of various situations, what how base station side knew UE feedback is the combination of which node, this point need to have a unified regulation in base station side and UE side, otherwise base station side cannot be known the combination of the polymerization CQI and which node that receive feedback.

Feedback for R10 mainly can be divided into periodic feedback and non-periodic feedback.

For non-periodic feedback, need uplink authorization or random insertion authority control signal to trigger non-periodic feedback.For non-periodic feedback, need uplink authorization or random insertion authority control signal to trigger non-periodic feedback.Aperiodic feedback model is as shown in table 1, can be divided into following several:

4,8,9 will the value based on RI determine, for the value of other transmission modes RI, equal 1 calculated value of determining CQI.Subband CQI for mode 3-0 and mode 3-1 adopts differential feedback.The subband feedback of selecting for UE comprises pattern 2-0 and 2-2.CQI and a broadband CQI that for pattern 2-0 end side, need to feed back a M Prefer subband, for transmission mode 3, the calculating of CQI need to be considered different RI values, for the transmission mode except mode 3, all supposes that RI=1 calculates CQI.For pattern 2-2 end side, need to feed back the PMI of a M Prefer subband and the PMI in a broadband, need in addition to feed back CQI (PMI based on a M Prefer subband calculates) and a broadband CQI (PMI based on a broadband calculates) of a M Prefer subband.

By the semi-static configuration of high level, as shown in table 2 for periodic feedback, can be divided into following several:
